Answer:
Difference threshold or also Just Noticeable Difference
Explanation:
The above mentioned case between room mates, where one room mate was able to detect a minute change in volume shows an instance of the difference threshold.
Difference threshold can be defined as stimulation at its minimum level that can be detected by an individual almost 50 % of the times.
It is the lowest possible level of sound that is detectable by a person.
That is what happened in the mentioned case that when the volume was increased from 14 to 15, Amber was able to detect it.
Answer:
41.07 m
Explanation:
According to the data:
Velocity = 2.65 m/s
Time = 15.5 s
Now the formula to calculate the distance is
Distance = Velocity x Time
Distance = 2.65 x 15.5
Distance = 41.07 meter
Kindly note that the person suddenly started to run at the velocity which is mentioned later that is 2.65 m/s.So the velocity given before is just ignored and we don't have to use any of the three equations of motion of kinematics.
Your answer would be 94. This is because only 10 transfers, so 90 is lost from the mouse. It takes 4 for the cat to pounce. When you add 90 and 4 you get your answer.....94
Con la cinematica podemos encontrar la distancia recorrida antes de detenerse es 169,96 m
Parámetros dados
- velocidad del camión v= 100 km/h
Para encontrar
- La distancia para detenerse
El sistema internacional de medidas (SI) es el sistema que deben tener todas las unidades del ejercicio, este es el primer paso si se tiene una mezcla de unidades
v= 100 km/h ( 1000 m/1 km) ( 1 h/3600 s) = 27,78 m/s
La cinemática estudia el movimiento de los cuerpos, estableciendo relaciones entre la posición, la velocidad y la aceleración
v² = v₀² – 2 a x
Donde v y v₀ son las velocidades inicial y final, a la aceleración del cuerpo y x la distancia recorrida
En este caso como el vehículo se detiene su velocidad final es cero
0= v₀² – 2 a x
x =
Calculemos
x = 27,78² / 2 2,27
x = 169,96 m
En conclusión usando la cinematica podemos encontrar la distancia recorrida antes de detenerse es
x= 169,96 m
